BLACKSMlTHS HAMMER.

SPECIFICATION forming part of Letters Patent No. 664,693, dated December 25, 1900. Application filed August 25, 1900. Serial No. 28,050. (No model.)

To all whom it' may concern: working parts of the machine are carried by Be it known that I, JACK WADE, a citizen a supporting stand or frame `1, essentially of the United States, residing at Lexington, comprisingapairofoppositely-arranged main in the county of Holmes and State of Mississtandards 2, connected by a plurality of cross- 55 sippi, have invented a new and useful Blackbars 3 and supported at their lower ends smiths Hammer, of which the following is a upon suitable legs-l..

The fixed rounded bearing-head 11 at the rear extremity of the brace or brace-bar 12 lies upon the spring-support 6 beneath the hammer-carrying spring 8 and within the vertical plane of the bearing-offset of said spring, and a slotted keeper 17 embraces the bearing-joint, consisting of the offset 1() and the head 11, and projects a material distance above the said offset 10 to accommodate the vertical play of the hammer-carrying spring at this point.

In connection with the construction just described it is to be observed that the rounded bearing-head 11, by reason of being located in advance of the fixed end 9 of the hammercarrying spring, necessarily in some measure acts as a fulcrum-point therefor, but in its ordinary function the said fixed head 11 serves to brace the fast end of the hammer-carrying spring and relieve it from undue strain during the operation ofthe hammer. Inasmuch as the offset 10 of the ham mer-carrying spring will loosely work over the rounded head 11, it

thus provides what might be'properly termed a pivotal joint for the hammer-carrying spring at its fixed end, which will greatlyincrease the freedom of action of the spring, besides relieving its fastenings from undue strain.

The vibratory hammer-carrying spring 8 is designed to have tted to the free swinging end thereof the swinging or vibratory hammer 18. The hammer is of any of the usual forms employed by blacksmiths, and essentially consists of the handle 19 and the hamme r-head 20, the latter being designed to work over the anvil 21, with which the machine or oliver is associated. The hammer-handle 19 is provided with one or more cuffs 22 at the end thereof opposite the hammer-head, which cuffs are `formed with engaging loops 23, offset from one side of the hammer-handle and adapted to receive therein the free end of the spring 8. The cuff or cus of the hammerhandle are tightly slipped over the front end of the hammer-carrying spring to provide a tight slip-joint connection between the hammer and the spring, so Vthat the same will move or vibrate in unison, while at the same time permitting the hammer to be readily detached and used as an ordinary hand-hammer, should this be desired.

To provide for mechanically operating the hammer in connection with the vibratory carrying-spring therefor, the hammer-handle is designed to have loosely and detachably connected to an intermediate point thereof, as at 24, the upper end of a link 25, the lower end of which is loosely connected to an intermediate portion of the inner section 26 of the sectional treadle 27, consisting of the said inner section 26 and the outer shiftable section 28, loosely united at their contiguous ends, as at 29, by a coupling or joint permitting of the outer section 28 being swung around or shifted to any convenient position for the operator. The unattached end of the outer shiftable section 28 of the treadle is designed to rest, upon the floor or ground, while the end of the inner'treadle-section 26, opposite its connection with the section 28, is pivotally mounted, as at 30, upon the machine stand or frame 1. The hammer is guided in its vertical movement or vibration by the up- 'right slotted hammer-guide 3l, loosely receiving therein the ham mer-handle 19 and secured fast to one of the cross-bars of the machine Ystand or frame. Y Y Y It is desirable in the use of the machine orVV oliver to provide means for adjusting or regulating the stroke of the hammer 18 to suit the conditions of the work to be accomplished.

This is effected through the medium of a,Y

stroke-adjusting device associated with the hammer-carrying spring 8, and in the present invention this stroke-adjusting device essentially consists of the transversely-arranged adjustable fulcrum-bar 32, a holding-bar 33,

and adjusting-screws 34. The said holding- Y Y bar 33 extends transversely across the machine stand or frame and receives at its opposite ends the lower extremities of the adjusting-screws 34, which are adjustably mounted in the threaded openings 35 in the opposite side bars 5 of the machine stand or frame.V Y Y loo .Y v

The transverse fulcru m-bar 32 is provid-ed at its ends with perforated ears 36, loosely receiving the adjusting-screws 34 and resting upon the holding-bar 33, and the said fulcrum-bar 32 is preferably of a bowed formation, so as of the herein-described mechanically-operated hammer or oliver will be readily apparent to those skilled in .the art without further description, and it will be understood thatVV various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle orV v sacriicing any of the advantages of this invention. z
